“That They All May Be One: Christ’s Prayer for Dogmatic Unity, Not False Ecumenism (see video at end!)

Among the most frequently misused words of our Lord are those spoken in His High Priestly Prayer:


“That they all may be one” (John 17:21)


These sacred words are often quoted today as a justification for every form of ecumenical compromise, interfaith prayer gatherings, and a vague sentimental unity that ignores truth for the sake of appearances. We are told that unity itself is the goal, regardless of whether that unity is founded upon the right confession of faith.


But this is not what Christ meant.


Our Lord did not pray for a unity without truth. He did not ask for agreement without doctrine, nor for prayer without confession, nor for peace without dogma. The unity for which Christ prayed is unity in Truth—dogmatic unity, unity in the Orthodox Faith, unity in the confession delivered once unto the saints.


Christ Himself says:


“Sanctify them through Thy truth: Thy word is truth” (John 17:17)


Notice carefully: before He speaks of unity, He speaks of truth. Truth is the foundation. Unity without truth is not Christian unity—it is merely organized confusion.


The Church is not united by emotion, diplomacy, or mutual tolerance. She is united by the right confession of the Holy Trinity, the Incarnation of Christ, the Holy Mysteries, the Apostolic Faith, and the unchanging dogmatic inheritance of the Fathers.


This is why the Holy Fathers never understood unity as coexistence with heresy.


Saint Mark of Ephesus did not say, “Let us unite despite our differences.” He stood firmly because he understood that without dogmatic truth, there can be no true communion.


Likewise, the Psalmist declares:


“Behold, how good and how pleasant it is for brethren to dwell together in this…” (Psalm 132/133)  Ἰδοὺ δὴ τί καλὸν ἢ τί τερπνόν, ἀλλ᾿ ἢ τὸ κατοικεῖν ἀδελφοὺς ἐπὶ τὸ αὐτό


The Fathers explain that this dwelling together is not merely physical closeness or social harmony. The Greek understanding of this togetherness—ἐπὶ τὸ αὐτό (epì to autó)—signifies being gathered into one mind, one confession, one faith. It is not simply standing side by side; it is standing upon the same truth.


This ἐπὶ τὸ αὐτό (on this) is dogmatic unity.


The Apostles were together ἐπὶ τὸ αὐτό because they shared one faith. The early Christians were together ἐπὶ τὸ αὐτό because they confessed one baptism, one Lord, one Church.


To pray together while believing differently about the nature of the Church, the Holy Mysteries, the priesthood, or salvation, or the very nature of Christ by itself is not the unity Christ prayed for. It is a counterfeit unity—a unity of appearance, not of substance.


Orthodoxy does not reject unity.


Orthodoxy insists upon true unity.


The Church prays constantly “for the union of all,” but this means union in repentance and return to the Truth, not the lowering of truth to accommodate error.


Love without truth becomes sentimentality. Truth without love becomes pride. But true Christian unity is both: love in truth.


Our Lord did not say, “that they may appear as one.”


He said:


“That they all may be one; as Thou, Father, art in Me, and I in Thee”


This divine unity is not vague cooperation. It is perfect harmony of being, truth, and will.


So must the unity of the Church be.


Not diplomacy.


Not compromise.


Not shared ceremonies without shared faith.


But one faith, one confession, one Church.


To seek unity without dogma is to build upon sand.


To preserve unity in Truth is to remain in Christ.


And therefore, to borrow the spirit of William Shakespeare:


To thine own faith be true.


For only then can we truly be one.
